7 is the window regulator having the mounting plate 8, `which is preferably stamped from sheet metal and is secured to and depends from the lock board 3 near the hinge pillar 1. 9 is the crank or handle of the window regulator, which through suitable drive mechanism operates the lifter element 10,l which latter is operatively connectj ved to the window 6 to.4 raise and lower the same. The lifter element comprises the lifter arm 11 and the gear segment 12, both be-A ing preferably formed from sheet metal and the former being in the plane of and at one edge of the latter. This lifter arm is set into and welded to the gear segment as at 13. The gear Ysegment is Xedly secured to the pivot 14, which is journaled in the lower end portion of the mounting plate 8 below the ook board 3, the lifter element including the gear' segment and lifter arm being adjacent theV outer side of the mounting plate. 15 is a convolute counterbalancing spring adjacent the inner` side of the mounting board andhavin its inner end engaging in the diametrica slot 16 of the pivot 14 and its outer end ioo tudmal median line of and preferably 1n` te al with the mounting plate.

he driving connection between the crank I or handle and the lifter element comprises the pinion 25 and the irreversibledrive mechanism 19.

The pinion 25 meshes with the gear seg-` ment 12 and the ratio of the numbers of` teeth of the pinion and gear segment is such that approximately one turn or revolution of the pinion moves the lifter element and more particularly the lifter arm through its complete operative arc to raise the window from its lowermost or fully open position to its -uppermost or fully closed position or to` lower the window from its uppermost or 4 fully closed position to its lowermost or fully open position. As shown in thepresent instance, the gear segment has some teeth at its ends which' do not intermesh with the teeth of the pinion, while the lifter arm is being moved through its complete operative arc, these extra teeth being present to take care ofany variations in location of the window regulator in the door or relative to the travel of the window.

vThe irreversible drive mechanism is proportional to the ratio of the numbers of teeth of the pinion and gear segment to effectively lock the lifter element and more particularly the lifter arm in its various positions of adjustment. The driving member of this irreversible drive mechanism comprises the shaft 20 and the cupped sheet metal member 21 fixedly secured to the'shaft 20 and having diametrically opposite transverse lingers 22. The driven member of the irreversible drive mechanism comprises the cupped sheet metal member 23, having diametrically opposite fingers 24, and the bushing 26, which fixedly secures the pinion 25 to the cupped member. 23. The fingers 24 engage between the fingers 22 and both sets of fingers are surrounded by a coil spring 27, which has a strength proportional tothe ratio of the numbers of teeth of the pinion and gear segment and isl provided with inturned ends located between one ofthe iingers 22 and on opposite sides thereof and the fingers 24. The housing for the irreversible drive mechanism comprises the sheet metal cup 28 and the cupped sheet metal plate 29, the cupped .driving and driven members 21 and 23, respectively, and the coil spring 27 being housed within the cup 28 and the spring beingadapted to normally frictional` ly engage t e inner periphery of the cup. This cup has at its outerl end the cylindrical flange 30 in Vwhich the portion of the shaft flanges symmetri- Voperative arc u 20 adjacent the crank is journaled. The cupped plate 29 has ixedly secured thereto, and thereb supports, the pin 31 which extends axia t rough the bushin 26 and into the sha t 20. and terminates su stantially opposite the cylindricalv flange 30. This pin thus forms an additional bearing for the shaft l20am). also forms a bearin for the driven member of' the irreversi le drive mechanism. The lower peripheral portion of the cupped plate is-outwardlyoifset at 29 to provide for passage of the ar segment fatpthe innerside ofthe web o the cupped plate. v

With this arrangement it will be seen that the irreversible drive mechanism may be direct-ly actuated by the crank or handle and that the dirven member of the irreversible drive mechanism is rotatable with the crank or handle after the slight lost motion of the crank vor handle necessary to release the coil spring from locking engagement has taken place. As a result, the lifter element and more particularl the lifter arm 'may be moved through its complete operative arc with approximately ono turn or revolution of the crank or handle, thereby making the window regulator a .quick vaction or high gear window regulator. The strength of the irreversible drive mechanism bein proportional to the ratio of the teeth of t e .pinion and gear segment, this mechanism seryes to effectively lock the lifter element and more particularly the lifter arm in its various positions of adjustment.

The crank or handle 9 is adapted to be fixedly secured to the inner end of the shaft 20 and has a length proportional to the ratio of the numbers of teeth of the pinion and gear segment so that the window regulator may be readily and easily operated thereby. This crank or handle is, however, relatively -short as compared to the crank or handle of any quick action window regulator heretofore' developed andthe mounting plate 8 is so positioned that when the knob ofthe crank is in its furthermost advanced position relative to the door it terminates short of the edge of the window at the hinge'ed'ge of the door.

The mounting plate has a width also proportional to the ratio of the numbers of teeth of the pinion and gear segment to withstand the driving force required to move the lifter element through its arc. This mounting plate is furthermore provided with the spaced lonf `tudinally extending relativel shallow reiinforcing ribs 8 z to assist -in hol ing the lower pcrtion'of the mounting plate from flexing laterally upon application of driving force to move the lifter element through its arc.

While the window regulator as above: described is constructed to eiect the movement of the lifter element through its complete n approximately one turn or revolution o the crank or handle or the pinion, the parts are so desgnedthat when assembled to form the window regulator, the size and' particularly the thickness of the window regulator is such4 that it may be properly positioned in the door 'andconnected-to the window for ready operationxwithout changing the door construction.

To provide for usingthe crank or handle 9 yas a pull-to handle for the door without damaging the window Aregulator andmore particularly the irreversible drive mechaplace as by means of suitable rivets, which extend through thek mounting plate.

The lower eripheral portion of the cupped plate 29 pre erably has the inwardly extend-y ing bosses 292 and themounting plate 8 preferably has the outwardly extending bosses 8 Itoenga e and guide the gear Segment."

It is hig ly important to eliminate'all possible frictional resistance to the` movement of the parts of the window regulator or'the window. This is accomplished by eliminating the frictional resistance between the con-'i volutions of the counterbalancing spring, by reducing to the minimum the frictional resistance in the connection between the lifter arm and the window, andby reducing to the minimum the frictional resistance offered to the movement of the window itself at the same time maintaining a good seal, a'voidingfrattling, vandr providing for large variations in the thickness and width of the window asY well as distances between the hinge "and lock pillars of the door. u

To eliminate friction between theconvolutions of the counterbalancing spring 15, there are the transverse projections 33 upon the lower end portion of the mounting plate 8 and preferablyintegral therewith, these projections being in the nature of transverse flanges for reinforcing the mounting plate. There are ,two of these projections arranged symmetrically on opposite sides of the longitudinal median line of the mounting plate, each having aconcave portion 34 which 1s substantially concentric with the axis of the pivot 14. These concave portions are alternatively lengageable with lthe outer convolution of the counterbala'ncing spring to thereby hold'v the same more trulycircular, which operates toY hold the remaining convolutionsmore truly circular and out of contact with. 'ea`ch other.

` Specifically, the concave portion inengage-l ment with the counterbalancing spring is onA the side ofthe longitudinal medianfline of the mounting plate opposite to the transverse lug 18 Aengage by the hook 17 of the spring.

xedly secure width of t reason of this arrangement the onev mountin late may be'used either with a rightI or le t andwindow regulator.

To eliminate all ossible friction in the' connection between t e lifter arm -11 and the window 6, the` lass -forming the window has dg toits lower vedge the-'sheet l metal channel 6 towhich is fixedly secured the retainer 35 having a depending Viiangel which is vertically bowed outwardly and is formed with vertically spaced longitudinallyy extending return bent portions 37 between its upper and lower edgesvv formin a lon '-2 tudinally extending slot. 38 is a g 1 pm fixe secured to the outer end of the lifter arm and extending outwardly through the slot and havingat its outerendthe head 39 forming a shouldered portion for engagin the outer sides of the return bent portions. he shoulderef the head is held in engagement with these returnv bent portions as by means of tlie coil splring 40 encircling the pin and abutting t By reason of the return bent portions, smooth bearin surfaces are obtained so that they offer t e minimum frictional resistance to 'ance to the movement of the window, at the f, same time maintaining a good seal and taking care' Oflarge variations inthe thickness an well as distances between vthe` illars, the means for guiding the glass inclu es the pairs of upper and lower runways 42 and 43 at the opposlte edges of the glass, theupper runways extendin downwardly to a-position to overlap the g ass when in its lowermost position e lifter arm and the concave4 washer 41, which 'latter also encircles the pm and` abuts the inner side of the dependingiange.

e glass lforming* the window, as

and the lower runways lablusting the upper runways. Each of the lower runways has `a sheet metal channel-shaped strip 44 anda linin 45 of'ibrous material, such asfalt,

whic is permanently secured to the metal strip as by ybeing cemented thereto. Rolls` 46 of relatively large diameter run in these lower runways, these rolls being mounted".r

upon the brackets` 47 which are tixedly secured to the channel 6 near its ends.

The upper runways are highly flexible to take care of the variations previously noted l and also to take care of misalignment of the lower with the upper runways, which latter might'occur during commercial manufacture. Each.` of these up er runways hasthesheet metal retainer strip 48'which is suitably se- 'p cured tothe hinge and look pillars and which has at its opposite edges the transverse flanges l 49, from which= are severed the tongues 50, which are bentV inwardly to em- 'brace the resilient strip 51, preferably formedl ofrubber, and to' secure this strip to the retainer strip. 52 are sheet metal side'strips,

' which is constructed to fit and be properly f that we have provided a simple construction tances between the which have their inner portions formed with the' transverse'foot flanges 53 extending under the resilient strip 51 andclamped there,-`

by against the ybase lof the retainer strip 48.

e inner portions of vthese side strips are cut away to form sections between which the tongues 50'passand the side ed es of the sections are spaceda suicient istance from the side ed es of the tongues to provide suicient lengxs of the resilient strip therebetweenfto allow the,V Asidev strips to separate through a relatively wide range.l The side strips have the continuous outer portions 54 which are located outwardly beyond the.

transverse vflan es 49 and converge toward each other an terminate in beaded out-er ed es 55. 56 is a fabric which is of agenera channel shape, but has its sides convergfrom its base to itsouter ed es. This in fabric is preferably formed of fe tand its secured to the resilient,

lFurthermore, by reason of the arrangement of the side stiipsand resilient strips in which the outer ortions ofthe side strips are yieldf ably hel against the glass by a resilient strip,y and also by reason ofthe relatively large rollsrengaging in the lower runways, the glass guideway takes care of large variations in the width of the glass and in the disillars and at the same time maintains` an e ective seal. y

From the above description it will be readily seen that we have yprovided for using a quick'action or high gearkwindow regulator,

positioned inl a standard construction-of ve-` hicle body andwhich, moreover, maybe operated with substantially the same eort asV required for the ordinary slow action or low gear-window regulators. It will also be seen of window regulator which permits using the crank or handle as a pull-to handle for a door Awithout liabilityof damaging thev window regulator. It ,willifurthermore be seen that the arrangement is such that frictional resistance throughout is either removed or re# duced to the minimum. p Y- What weclaim as our invention is: A 1.
